Uses of PolyDADMAC

1. Effluent treatment

Poly DADMAC is used in waste water treatment as a primary organic coagulant which neutralizes negatively charged colloidal material and reduces sludge volume compared with inorganic coagulants.

2. Pulp and paper industry

PolyDADMAC is used for controlling disturbing substances in the papermaking process. It provides superior fixing of pitch from mechanical pulp and of latex from coated broke. Used in the short circulation of a paper mill to enhance retention and dewatering. In addition, it can be used to improve the efficiency of disk filters and flotators, and for cationization of fillers to provide maximal filler retention.

Poly DADMAC can also be used as a flocculant to improve soap separation process in the evaporation plant of kraft pulp mills thus contributing to higher tall oil yield.

3. Water purification

Poly DADMAC is used as flocculant in water purification. It is very effective in flocculating, decoloring, killing algae and removing organics such as humus. 

Few dosage generates large flocs, rapid precipitation and low turbidity residue.
